Demonstration of the use of SLIDE A2 (0.5mm GRID) for measurements.

The White sun

Well, we have read that white is the actual color of sun and so today morning hours I observed it at Haldwani,  Uttrakhand. By Abhijeet Singh Dewari from Lakes International School

Bubble wrap under microscope

I saw a bubble wrap under Foldscope and found this, Dont know the exact about the structure but there seem some small air sack like structure . with

Fern spore catapult

I planted a fern in my garden a couple of months ago and ferns have been taking over! I’m not sure about the species — Ostrich fern (Matteuccia orientalis)? I remember learning about fern reproduction involving some strange alternation of generations with ‘spores’ that grow on the underside of leaves. Sure enough, there were a…

Diffraction of light by single slit

I have performed an experiment in physics lab of Kokrajhar Govt. H. S.&M. P. School on diffraction of light by single slit made of two blades. Two blades  are joined length-wise using cellotap with a separation of 1 mm in between. The slit is then placed in position of slide in the Foldscope. Laser(red) is…

A simple hack for reflection/epi-illumination using the foldscope

I have been wanting to post on this for long. There is a very simple way to achieve reflection/epi-illumination microscopy in the new foldscope. For this, I use a simple LED hack that was described by Marie. See https://microcosmos.foldscope.com/?p=13486.  This LED unit can now be inserted from the side as seen in this video. The video…

Fun time with fibres and other things

From the clothes we wear to the paper on which we write, these things are made of fibres. Fibres of polysaccharides. Just how amazing these look under a foldscope…   Paper may look smooth and uniform as viewed from the naked eye, but microscopically a different story is seen.     Cotton fibres seen through…

Happy Birthday, Mr. Carl Zeiss!

On September 11, 2016 the town of Jena, Germany, celebrated the 200th birthday of Mr. Carl Zeiss. I am sharing here some impressions from the personal life of Mr. Carl Zeiss – one of the great pioneers of microscopy – as told through the events of his 200th birthday celebration. Carl Zeiss Jena was originally…

How aperture affects image quality

When I first heard about Foldscope from a friend in 2016 I became curious. Until my Foldscope arrived in early 2018 I started experimenting with ball lens microscopes myself. Please see a photo of some of my models. When I first used my new Foldscope, I was impressed with the good image quality. I attribute…

Capillary action occuring on paper

One thing we often do while preparing any wet mount is removing excess of mounting medium; mainly by making use of blotting paper. Wondered how blotting paper takes up the excess medium so quickly? A phenomenon called capillary action comes into play. Blotting paper consists of several hydrophilic substances and water (most common mounting media)…

Going electronic

Observing this wasn’t planned exactly before, though boredom got the best out of me. Studying for exams were a bit tedious thing… hence this is what I did. Armed with a foldscope, all I could see was my target which was the computer screen, which had all ebooks in it which I was reading at…

Polarized explorations part 2

Hello everyone, There are going to be tons of pics in this post so I better limit the words. I have foldscoped 3 compounds here – Citric acid , L-cysteine and Potassium dichromate. Recrystallized Citric acid Just while I was foldscoping these citric acid crystals an orange caught my attention! I thought Why not try…

Polarized light foldscopy

I finally got myself a polarizing film. By this I can now polarize the light falling on the sample by placing the film between the light source and the sample and further by placing another film between the lens and the eye/camera I can block the same polarized light so that only light whose polarization…

Recrystallization And A Question

Hello Everyone, This time I’ve tried making a time lapse of NaCl getting recrystallized. I have used dark field here to make the crystals look more prominent. Here are the steps I followed: 1. Prepare a saturated solution of NaCl I.e adding NaCl to water till it stops dissolving. 2. Put a drop of this…

Butterfly scales through the lens of a Foldscope

I was really excited to receive a new Foldscope kit recently, and after corresponding with Manu online, we agreed that butterfly scales represent a nice project that others can easily get involved with! Here are some previous posts on the subject: https://microcosmos.foldscope.com/?p=10080, & https://microcosmos.foldscope.com/?p=16562 Here’s magnification of a butterfly eyespot and through the lens of a #Foldscope below,…

Tutorial: Surface imaging using Foldscope – ice formation

I want to start the year with new year spirit. Ice crystals. It’s -26C here; yes – you read it right. Most people are enjoying the fact that it’s colder in Montreal than Antarctica. Something we should be worried about; but that’s for another day. Basic foldscope can be used for surface imaging on translucent…

Inculcating Research Culture Right From Schools

As a part of TIFR, Hyderabad’s efforts to facilitate better science education in the local schools, it now interacts closely with four of the Telangana Social Welfare Residential Schools, all within 10 km from the institute. On regular close interactions with the teachers and students alike from the schools, we realized that schools are fast…

Mystery of the moth scales!

Happy Diwali Everyone, Moths are pretty rare here in Mumbai. This little guy flew in my window a few days a ago and landed directly on my arm. I have wanted to observe butterfly or moth scales since a very long time and I didn’t want this guy to flee before I could observe it’s…

Hacking A Lower Powered Foldscope

Recently, I decided to undertake a search for micrometeorites (you can read more about them here). Since a good portion of micrometeorites are ferrous, you can use a magnet to search for them. However, not all samples of ferrous particles are potential micrometeorites, so you  will have to examine them. I already have a handheld…

Comparing outdoors vs table lamp based illumination 

Here I compare outdoors afternoon light as illumination with a regular table lamp illumination; to give foldscope users a perspective on how to select light. Also; I tried an informal narration mode in the video itself. I will do more of these live narration videos to both improve my craft of telling a story on…

Nothing is sharp even if paper cuts your hand

Recently i got a paper cut in my finger while i was writing my assignment. I asked myself how is this even possible DROP ASSIGNMENT TAKES THE PAPER OPENS BOX TAKE THE FOLDSCOPE MINDBLOWN. Though it was cut highly presise by machines in the industry , its not.  I was even able to see the…

Queen Ant wings

  A few days back ,I saw ants near the door and an insect with wings that  i belive  the Queen ant (motionless). Then I saw that the wings were different there were colourless patches in some area . First time in my life I wilfully plucked a wing ,gave me chills though it was…

Video: Middle School Tech Review

Real tools lead to real work at Opportunity Middle School in Concord, NC. Using microscopes, foldscopes, and laser lens hacked cheap fire tablets, our students are opening up their world, all on their own. With only a couple of takes after stumbling over the term “microscope,” these 7th and 8th graders free-styled this video to…
